GSM communicator 485COM

Wireless data transmission from electronic meters
 485COM communicator designed for wireless data transmission from electronic meters via GSM network.


Communicator designed for wireless data transmission from electronic meters via GSM network.

Data can be transmitted in the case of continuous measurements using GPRS data transmission or for the non-continuous measurement using SMS messages.

The GSM communicator 485COM is being used in applications where, for technical, economic reasons or because of mobility the data transmission over landline cannot be realized.

To one GSM communicator several electronic meters can be connected (electrometers, network analyzers, gas meters, flow meters, heat meters and others). Via the serial interface RS485.

  • Wireless data transmission

    Based on the volume and frequency of the transmitted data you can use:

    GPRS data transmission (suitable for continuous metering – online measurements in real time)
    transmission via SMS messages (suitable for non-continuous measurements – eg. the measurement once per day, week or month)

  • Serial interface RS485

    Electronic meters can be connected via RS485 serial bus protocol supporting MODBUS and IEC 62056-21.

    You can connect for example electrometers, network analyzers, gas meters, flow meters, heat meters, and other atypical meters or sensors with RS485 output.
    Several meters can be connected to one GSM communicator.

  • Variable use

    We designed the device to be flexible so it can be adapted to customer requirements..

  • Small dimensions and easy installation

    The device was designed into a 2 module box with DIN rail mounting. It is possible to connect an external magnetic GSM antenna if needed.

  • Communication and control

    The big advantage of 485COM is its ability to communicate and operate through its own software applications or the possibility to integrate the communication into the customer’s existing systems.

    For non-continuous measurements we offer our specialized software 485COM Monitor.

  • Virtual COM port driver supplied by FabulaTech LLP company.
